Summary 0003009: NullPointerException when Resin-3.1.7a is killed using ./httpd.sh kill
Description [2008/10/19 15:59:16.059] WatchdogProcess[Watchdog[],1] stopping Resin
Exception in thread "watchdog-" java.lang.NullPointerException

Steps to reproduce:


Resin was started with

 Just to make it clear:
Normally Resin is stopped with './httpd.sh stop' and that works as expected without a NPE.
Just in case one would kill Resin with './httpd.sh kill' a NPE should be avoided when possible.
